Buck-Boost Converters for Portable Systems

This topic presents several solutions to a typical problem encountered by many designers of portable power — how to produce 3.3 V from a single-cell Li-ion battery. The advantages and disadvantages of each solution are provided along with measured data on overall battery runtime. This data helps the designer select the best overall solution for specific system requirements. This topic also provides a detailed comparison of the Texas Instruments (TI) fully integrated TPS63000 buck-boost converter and other buckboost solutions. The efficiency, overall ease of use, and operation in “transition mode” — when the converter switches from buck to boost mode — are discussed.
